Prism ya Quartz yosakanikirana
Chithunzi chatsatanetsatane
Chidule cha Quartz Prisms
Ma prism a quartz ophatikizika ndi zinthu zofunika kwambiri zowunikira zomwe zimagwiritsidwa ntchito kuwongolera, kuwongolera, ndi kuwongoleranso kuwala mumitundu yambiri yowoneka bwino kwambiri. Zopangidwa kuchokera ku silika wosakanikirana kwambiri, ma prism awa amapereka mawonekedwe apadera otumizira ma ultraviolet (UV), owoneka, komanso pafupi ndi ma infrared (NIR). Ndi kukana kwamphamvu kwamafuta ndi mankhwala, mphamvu zamakina zabwino kwambiri, komanso kuphatikizika pang'ono, ma prism a quartz osakanikirana ndiabwino kuti agwiritsidwe ntchito movutikira mu spectroscopy, laser optics, kujambula, ndi zida zasayansi.
Fused quartz ndi mawonekedwe osakhala a crystalline, amorphous a silicon dioxide (SiO₂) omwe amawonetsa milingo yotsika kwambiri yonyansa komanso mawonekedwe owoneka bwino kwambiri. Izi zimathandizira kuti ma prism a quartz azitha kuchita mosasokoneza pang'ono, ngakhale m'malo ovuta kwambiri.
Zinthu Zakuthupi za Quartz Prisms
Fused quartz imasankhidwa kuti ikhale yopanga ma prism optical chifukwa cha zida zake zapadera:
-
High Optical Transmission: Kuwala kwapamwamba kwambiri kuchokera ku ultraviolet yakuya (185 nm) kudzera pakuwonekera mpaka pafupi ndi infrared (mpaka ~ 2500 nm), ndikupangitsa kuti ikhale yoyenera pa ntchito zonse za UV ndi IR.

FAQs - Mafunso Ofunsidwa Kawirikawiri a Quartz Prisms
Q1: Kodi pali kusiyana kotani pakati pa quartz yosakanikirana ndi silica yosakanikirana?
A: Ngakhale kuti mawuwa nthawi zina amagwiritsidwa ntchito mosiyana, "fused quartz" nthawi zambiri amatanthauza galasi la silika lopangidwa kuchokera ku makristasi achilengedwe a quartz, pamene "silica wosakanikirana" amapangidwa kuchokera ku gasi wopangidwa ndi silica. Onsewa amapereka mawonekedwe ofanana, koma silika wosakanikirana amatha kukhala ndi kufalikira kwa UV.
Q2: Kodi mungagwiritse ntchito zokutira zotsutsa-reflective pa ma prisms a quartz osakanikirana?
A: Inde, timapereka zokutira zamtundu wa AR zomwe zimapangidwa kuti ziziyenda mosiyanasiyana, kuphatikiza UV, zowoneka, ndi NIR. Zopaka zimapititsa patsogolo kufalikira ndikuchepetsa kutayika kowonekera pamalo a prism.
Q3: Ndi mtundu wanji wapamtunda womwe mungapereke?
A: Standard pamwamba khalidwe ndi 40-20 (zikanda-dig), koma timaperekanso apamwamba mwatsatanetsatane kupukuta kwa 20-10 kapena kuposa, kutengera ntchito.
Q4: Kodi ma prisms a quartz ndi oyenera kugwiritsa ntchito laser UV?
A: Ndithu. Chifukwa chakuwonekera kwawo kwa UV komanso kuwonongeka kwa laser, ma prism osakanikirana ndi abwino kwa ma laser a UV, kuphatikiza ma excimer ndi magwero olimba.
